( Fig. 141 )

Oxathridia Gilmour, 1963: 7 .

Type species— Oxathridia roraimae Gilmour, 1963 (original designation).

Diagnosis. Scape not dilated at distal third; prothorax with obtuse protuberance at basal third; prosternal process about as wide as procoxal cavity; mesoventral process wider than mesocoxal cavity; apex of elytra obliquely truncate; ovipositor surpassing the elytral apex. The only specimen known, the female holotype, has only the scape of one antenna, and part of three legs. Number of species currently included: 1.

Remarks. As the only knonw specimen of Oxathridia is damaged, lacking most of its antennal segments, it cannot be included in the key by Monné et al. (2020).
